T o all whom it may concern:

Be it known that I, RUDOLF Linmsnu, .a subject 4of the Emperor of Austria-Hungary.I residing at Erie, in the county of Erie and State of Pennsylvania, Ahave invented new and useful Improvements in Sprinklers, ,of which the following is a specification.

This invention relates to sprinklers, and consists in certain improvements in the construction thereof as will be hereinafter fully described and pointed out in the claims.

The invention is illustrated in the accompanying `drawings as follows:

Figure 1 shows acentral longitudinal section through the sprinkler; 2 .a central longitudinal section of Vthe nozzle, .the section beingon the line .2-2 in Fig. 1; Fig. 3 a section on .the line 3-3 in 1, looking toward the -top of Fig. 1.

1 marks the supply chamber. preferably supplied with the screw threads l, adapted to be screwed onto the ordinary hose fitting. nects with the supply chamber 1. It has a flange 3 the two surfaces v.of which form race ways for ball bearings.

at 44, and the [lange cap 5 screwed onto Vthe screw threads 4. The flange 6 on this cap forms a race way opposing the flange 3, and a neck 7 on this flange cap is arranged around the rotating member. A washer 8 forms a race way also opposing flange 3, and the balls 9 are arranged on each side of the flange 3, and between the flanges 6 and 3 and the washer 8 and the flange 3, thus completing the ball bearing.l The spring 10 yieldingly holds the washer 8 against the balls. A joint surface 11 is arranged in the chamber 1, and the rotating member 12 has a similar surface.

he cap 4 is made adjustable so as to carry the member 2 into such relation with 'the member 1 that the surfaces 11 and 12 form a joint sufficiently tight to prevent eX- cessive leakage and still permit of easy rotation of the rotating member. The spring 10 permits of this adjustmentwithout disarranging the ball bearing. v*Where it is desired to entirely close the joint between the surfaces 11 and 12, this may be done by ad justing the cap 5 so as to crowd the surface 12 on the member 2, into close contact with the surface 1l on the supply chamber.

This is The rotating member 2 con-y openings 23, and are so 'llhe exterior` of the supply chamber 1 is screw threaded The rotating member 2 has `a valve `plug 13 formed on its upper end, and a nozzle 14 is mounted on this plug. The nozzle 14 has an axial j et end withI the nozzle. The nozzle preferably has Aa cavity 1G into which the jet end 15 is crowded. This cavity has .the shoulder 17 at ,the bottom, and a valve plug vextends through this shoulder having a screw threaded extension 18 in the cavity 16. The washer 19 is `arranged ,on this extensiorI against the shoulder 17, and an end l-20 is screwed onto the extension 18 against the washer. 1n this way the vvalve plug 13 is held in the nozzle.

The valve plug has a central opening .or

yway 21, and .the radial ways 23, the .valve plug being preferably closed at its outer end The ways 22 are adapted to fbe brought into lregister lwith the ways 23, forming radial jet openings. Vanes 24 extend from the nozzle in the .path of the jet from Vthe jet y deflected with relation to such jets that the nozzle -is rotated .by ,the force ofthe jets onithe afanes. The .vanes also spread vthe jets slightly, so that while they have sufficient force to cover a wide range, yet the spread of the jet Ais such as to cover this range uniformly.

ypasses 25 are arranged in the nozzle 14. These bypasses are quartering to the ways 23, the bypasses leading to a point in t-he nozzle to permit of the ways 22 being brought into register with the bypasses 25. The bypasses extend into the cavity 16, and consequently supply the axial jet. By turning the nozzle 14 on the valve plug, the ways 22 may be brought into register wit-h the ways 23 when a rotating sprinkler is formed. On the other hand, the ways 22 may be brought into register with the by passes 25 when an axial jet nozzle is formed. I prefer to provide the shoulders 26 and 27 on the nozzle, and a stop pin 28 on the plug, so as to locate the ways 22 with the ways 23 and the bypasses 25.

There the device is used with the axial jet nozzle, the cap 5 may be screwed down to form a tight joint at the surfaces 11 and 12 and the ways 22 being brought into register with the bypasses 25, the radial ways are cut off. Vhere it is desired to use the device as a rotating sprinkler, the ways 22 may be brought into register with the ways 15, separably connected 23 and the rotating member and supply member loosened suiiiciently to permit of the free rotation.

What I claim as new is:

l. In a sprinkler, the combinat-ion of a rotating member; a valve plug formed thereon having a radial Way therethrough; a nozzle mounted on the plug having a cavity in the end and having a radial jet opening adapted to be brought into register with the Way in the plug; and bypasses adapted to be brought into register with the Ways in the plug, and leading into a cavity in the end of the nozzle; and means arranged in the cavity in the end of the nozzle for securing the plug in the nozzle.

2. In a sprinkler; the combination of a rotating member; a valve plug formed thereon having a radial Way therethrough; a nozzle mounted on the plug having a cavity in the end; radial jet openings adapted to be brought into register with the Way in the plug; and bypasses adapted to be brought into register With the Way in the plug, and leading into the cavity in the end of the nozzle; means arranged in the cavity in the end of the nozzle for securing the plug in the nozzle; and an axial jet end screwed into the cavity.

3. In a. sprinkler, the -combination of a rotating member; a valve plug formed thereon having a radial Way therethrough; a nozzle mounted on the plug having a cavity in the end, radial jet openings adapted to be brought into register With the Way in the plug, and bypasses adapted to be brought into register With the Way in the plug, and leading into the cavity in the end of the nozzle; means arranged in the cavity in the end of the nozzle for securing the plug in the nozzle; and vanes on the nozzle 1n the pat-h of the jets from the radial openings.

4. In a sprinkler, the combination of a stationary member; a rotary member forming a joint with the stationary member; means for adjusting the joint; a valve plug on the rotary member; the plug having a radial Way therein; a nozzle mounted on the plug With a radial Way adapted to be brought into register with the way of the plug and a bypass adapted to be brought into register with the Way of the plug; and means actuated by the energy of t-he passing fluid for rotating the rotating membci.

5. In a sprinkler, the combination of a, stationary member; a rotary member forming a joint with the stationary member; means for adjusting the joint; a valve plug on the rotary member; the plug having a radial Way therein; a nozzle mounted on the plug having a radial Way adapted to be brought into register with the way of the plug and a bypass adapted to be brought into register with the Way oi the plug; and vanes on the rotating member in the path of the jet from the radial way in the nozzle.

In testimony whereof, I have hereunto set my hand in the presence of two subscribing Witnesses.
